For me, i have no idea why PS showcase only announced 2 first party games which is released in 2023 in beyond.
According to Shinobi's twitter post, there are some unannounced games released in 2022. This strategy is weird.
It might also be a Marvel thing as well. After the misfire of The Avengers they might want to increase confidence in the direction of their games division by showing they are doubling down on the game and team that delivered a huge critical and commercial success.
